To I/Z whom, t puny concern:

Be it known that I, GEORGE l/V. VEAR, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented a new and useful Improvement in Locking Wedge-Bolts on Locomotive-Pedestals or Vehicles, of which the following is a specification.

The object of this invention is to produce a wedge-bolt lock-plate that will permit of the adjustment of the wedge to its proper position and when once in that position prevent it from becoming unadjusted, a result which has not been successfully accomplished heretofore. I attain this obj ect by removing one or more segments from the body of the wedge-bolts and placing a lock-plate on the two bolts, which iit the removed segments and is held in place by j am-nuts, all of which will be described hereinafter.

I am aware that efforts have been'made to lock the wedges in place by locking each wedge separately.

I am not aware that a lock-plate consisting of a plate with two or more holes, which would be circular were it not for the segments remaining, has ever been used heretofore.

Referring to the accompanying drawings, which form a part of this specification, and wherein like letters of reference indicate like parts, Figure l represents the lock-plate in its simplest form of construction. Fig. 2 is a parted section of Fig. 3 at A B, showing the application of the lock-plate to the wedgebolt. Fig. 3 represents a locomotive-pedestal having the wedge-bolt lock-plate attached. Figs. 4 and 5 show the lock-plate in two parts, which is to permit of the adjustment of the wedge without removing the plate entirely.

I would prefer the plate to be made in one piece. It can be made in two or more, however, without departing from the principle of my invention.

In the drawings, S and S are the shoes, S being the wedge-shoe which adjusts t-he distance between the shoes. S has two openings which hold the two nuts N. Through these nuts are the wedge-bolts T, which force the wedge S up and down. WV is a washer which supports the bolts. The bolts pass through the binders G and have a segment removed from this body, so as to fit the lockplate L. The shape of the hole is shown by U. The jam-nuts J hold this plate L in place, and the wedge-bolts T cannot turn and change the adjustment as long as L is in place. Figs. 4 and 5 show the plate in two parts, so one bolt can be adjusted at a time without entirely remo ving the lock-plate.

A lock-plate as described keeps the wedge in place by locking the two bolts together, and thus holding the adjustment, as the jamnuts and plate must work loose and drop clear off before the adjustment can be changed.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a pedestal, of adjustable wedges 4carried thereon, wedgebolts supporting said wedges, and a lockingplate adapted to secure the adjustment of said wedges and bolts, substantially as described.

2.The combination with a pedestal, of adjustable wedges carried thereon, wedgebolts adjustably supporting said wedges, the lower portions of said wedge-bolts being segmental in cross-section, and a lockingplate adapted to secure the adjustment of said wedges, substantially as described.

3. The combination with a locomotivepedestal, of adjustable wedges carried thereon, wedge-bolts adjustably supporting said wedges, the lowerportions of said wedge-bolts being segmental in cross-section, a lockingplate having segmental openings therein adapted to receive the segmental portions of the wedge-bolts and revent their rotation, and jam-nuts carried on said wedgebolts, substantially as described.
